What are the Ultrasonic Testing (UT) Methods? Ultrasonic Testing (UT) Methods – Sound is a physical phenomenon, although its instantaneous existence is very obvious, but it does not cause any permanent changes. This is why sound (low energy) is ideal for nondestructive testing, where the state of the object under test is determined by obtaining accurate information. For this purpose, a method is needed that produces a definite reaction within the subject without changing its state. “Passivity” is the most important feature that sound is required for material testing. 1. Passive acoustics is also used in the special field of acoustic emission, in which sound waves are generated internally by spontaneous changes in material conditions. Sound waves are mechanical waves and therefore need to act as a medium for conducting them. Whether it is a solid, a liquid, or a gas, each material can be evaluated for its particular effects […]
